At every SERCAL conference, an individual or group is honored for their work furthering the field of ecological restoration. At SERCAL 2017 in Davis, we awarded Vic Claassen and John Anderson.
This 7.2-mile stretch of riparian habitat is the project area of the San Luis Rey River Flood Risk Management Project. For years, this portion of the San Luis Rey River was overgrown with many invasive non-native plants like giant weed (Arundo donax), salt cedar (Tamarix sp.), and castor bean (Ricinus communis). The high abundance of these exotics diminished the quality of the habitat for the federally listed species and added to the dense vegetation that could lead to the increase of flood risk.
Since its inception in 1944, the Water Authority has aimed to secure a reliable water supply for San Diego County and has incorporated environmental programs and sustainability into its business model. The Water Authority is committed to restoring plant communities that are disturbed or impacted as a result of construction activities, and to conserve natural resources that surround their right-of-way and facilities throughout MTRP.

In 2003, a single PSHB beetle was caught in a CDFA trap in Long Beach. The beetle went unnoticed until 2012 when it was found damaging backyard avocado and urban forest trees in the Los Angeles basin. A rapid monitoring response uncovered the broad host range of the pest-disease complex, but its ability to establish in native vegetation was only gradually recognized.
With the shot hole borer rise within Orange County and, on a larger scale, Southern California, these species are presenting new complications that affect not only the health of the system but also budget constraints associated with the restoration plan.
The polyphagous shot hole borer (PSHB), an exotic forest pest from Southwest Asia, is causing millions of dollars of damage and devastating native woodlands in California.
Thanks to every single one of our attendees, SERCAL 2016 in Tahoe was a giant success! Here are some of the highlights…
This article explores the differences in the two primary drone platforms, the various products they can produce, and a variety of applications pertinent to restoration ecology.
Our research has established performance and efficacy criteria that demonstrate the risk can easily be avoided by the application of solarization techniques between uses of pots and other horticultural containers.
With the broad range of plants susceptible to Phytophthora and other plant pathogens, there is the potential in restoration activities to inadvertently introduce Phytophthora-infected nursery stock into sensitive habitats, setting up a direct pathway for pathogen introduction and spread, and destroying the ecological values that restoration is trying to enhance.

In 2011, efforts for a large-scale habitat enhancement project in this section of the Little Truckee River began, first with characterization of the system’s functional impairments, followed by development of a conceptual habitat enhancement design.
Squaw Creek and the montane meadows of Olympic Valley are iconic of Sierra watersheds with prominent visibility as an international tourist destination. As Squaw Creek winds its way down from the Pacific Crest to the Truckee River, three landowners account for about 90% of the watershed’s land base. The protection, restoration, and enhancement of the Squaw Creek watershed warrants participatory collaboration amongst these landowners for the mutual benefit of the resource.
What do you get when you mix Caltrans, an environmental advocacy group, tufa soil (pH8.3), a 60-degree slope, and the need to make sure you can effectively stabilize that slope?
Adaptive management has become popular precisely because it has been recognized and shown that command and control structures are often not applicable to dynamic, complex, and oftentimes chaotic, natural processes. But what is adaptive management and does it work?
Invertebrates can be effective indicators of the consequences of non-native plant invasions due to the important functional roles that they play in ecosystems, including nutrient recycling and energy flow, pollination, seed dispersal, and the maintenance of plant and animal community structure.
As practitioners tasked to plan or evaluate restoration projects and meet permit requirements in freshwater habitats, we often neglect non-listed species. Half of all freshwater species in California are considered to be vulnerable to extinction, and extinction rates in freshwater ecosystems are 4 to 5 times higher than those of terrestrial systems.
SWAMP has developed a variety of tools for use in bioassessment, including indices for interpreting stream health based on biological data, taxonomic resources for identifying BMIs and benthic algae, and standard operating procedures for conducting field sampling and sample processing in the laboratory.
